If billy has 3 lemons and josh has 2 lemons then how many more lemons does billy

First we calculate the area of the entire dartboard which will constitute the total area. The total area is in the form of a circle with radius 15 inches

Total area = area of circle =

Total area =

Total area =

Next, we calculate the area of the bull's eye. Again the bull's eye is another circle whose radius is 2 inches

Bull's eye area =

Bull's eye area =

Probability that a dart thrown at random within the dartboard will hit the bull’s-eye =

Probability that a dart thrown at random within the dartboard will hit the bull’s-eye = 4/225 = 0.01777 = 1.77% = 1.8% (Option A)
